Abstract

PURPOSE:To select a precise word by retrieving a synonym retrieving dictionary when expression can not be detected in the case of composing a sentence. CONSTITUTION:When a synonym key 104 is depressed in an input means 1, a synonym retrieving means 4 is accessed, a synonym retrieval specifying word is collated with notation and a group number in a synonym retrieving dictionary 5 and a synonym is retrieved while collating it with the connection value of an input character string including the synonym retrieval specifying word. The dictionary 5 stores group numbers, notation and connection value information. A precise word out of retrieved synonyms displayed on a display means 7 is selected by depressing a selection key 105 and the selected word is substituted for the synonym retrieval specifying word by depressing an execution key 103.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus, and in particular, when an operator performs kana-kanji conversion and finds a phrase in creating a sentence, searches a synonym search dictionary,
The present invention relates to a document creation device used to select an accurate word.

[0002]

2. Description of the Related Art A conventional document creating apparatus is disclosed in Japanese Patent Laid-Open No. 4-14.
Some are disclosed in Japanese Patent No. 8466. FIG. 5 shows its block diagram. The document creation apparatus shown in FIG. 5 includes a character string storage unit 501, a paraphrase word dictionary 502, a notation information buffer storage unit 503, a notation information buffer 504, a notation information display unit 505, and a paraphrase word candidate selection unit 506. .

The character string storage means 501 stores an undetermined character string in the ordinary kana-kanji conversion in the notation information buffer 504.
To store. The notation information buffer storage unit 503 searches the paraphrase word dictionary 502 for a character string having the same notation as the undetermined character string stored in the notation information buffer 504, and if a character string having the same notation exists, the notation word The candidates and examples are stored in the notation information buffer 504 from the paraphrase dictionary 502.

The notation information display means 505 reads out and displays the paraphrase candidate and its example from the notation information buffer 504 when an instruction to display the paraphrase candidate is given. The paraphrase word candidate selection means 506 selects and selects the paraphrase word candidates displayed by the notation information display means 505.

[0005] In this way, for example,
Kana-to-Kanji conversion output was made by inputting "Caution", but when the operator instructed to display the paraphrase candidate in search of a more appropriate expression, in the case of a synonym as the paraphrase, "Be careful of ..." , "Warn about", and the like can be displayed together with examples to facilitate the operator's selection of the notation of the intended expression.

[0006]

The above-described conventional document creating apparatus can be expected to be effective for an operator who does not necessarily have sufficient writing ability to create a correct and beautiful sentence. However, when searching for paraphrases, Since all the synonyms including the synonyms and antonyms of the paraphrase are extracted and displayed on the screen, there is a drawback that it takes time for the operator to hesitate to select the most appropriate synonym.

Therefore, the object of the present invention is to solve the above-mentioned drawbacks and to display only synonyms that grammatically match the sentence structure of the input character string on the screen rather than displaying all the paraphrases on the screen. Therefore, the operator does not have to select a synonym that does not grammatically match the sentence structure of the input character string, and it is an object of the present invention to provide a document creation apparatus that can easily select an appropriate synonym.

In the present invention, the synonyms and antonyms to be searched are called "synonyms" and are also functionally distinguished from the "paraphrases" used in the prior art.

[0009]

The document creation apparatus of the present invention is a synonym search in which input means for inputting characters and symbols and valence information indicating the connection relation of the synonyms for searching synonyms are added. A dictionary, a synonym search means that searches for synonyms from the synonym search dictionary, a Kana-Kanji conversion dictionary to which information on the type of noun is added, a bond value (noun type and particle and noun) of input strings, and Kana-Kanji conversion It comprises a valence search means for collating the information on the type of noun in the dictionary with the valence information in the synonym search dictionary.

[0010]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the document creating apparatus of the present invention.

As shown in FIG. 1, the document creating apparatus of this embodiment has a character string key 101, a conversion key 102, and an execution key 1.
03, synonym key 104, selection key 105, and cancel key 1
And a kana-kanji conversion dictionary 2, a kana-kanji conversion means 3, a synonym search means 4, a synonym search dictionary 5, a valence search means 6, and a display means 7.

The character string key 101 of the input means 1 is used to input a character string (characters, numbers, symbols, etc.). Conversion key 10
2 is used to sequentially display a plurality of conversion candidates of the input character string on the display means 7. The execution key 103 is used for confirming a kana-kanji conversion candidate and for confirming a synonym selected and displayed in the synonym search. Synonym key 10
Reference numeral 4 is used to specify the search of the synonym search dictionary 5. The selection key 105 is used to select when there are a plurality of searched synonyms. The cancel key 106 is used to issue an instruction to cancel the call to the synonym search means 4.

FIG. 4 is a configuration diagram showing a configuration example of the Kana-Kanji conversion dictionary 2 shown in FIG. Kana-Kanji conversion dictionary 2
Is heading 401, frequency 402, notation 403, part of speech 40
4 and a noun type 405. The kana-kanji conversion unit 3 collates the input character string with the headline 401 of the kana-kanji conversion dictionary 2 and converts the input character string into the conversion candidate notation 403. For example, when the input character string is “Shingo”, the notation corresponding to “Singou” in the heading 401 in FIG. 4 is “Signal” in the notation 403,
Converted to "signal". Further, the frequency 402 is information in which the same phoneme is numbered in descending order of number of times of use.

FIG. 3 is a configuration diagram showing a configuration example of the synonym search dictionary 5 shown in FIG. The synonym search dictionary 5 is
It is composed of a group number 301, a notation 302, and bond value information 303, which are grouped according to the meaning of the word. The definition of valence here is that "elements that can be combined with a verb are the classification of case particles and the semantic classification of nouns (semantic features).
What is represented by "(quoted:" Kana-Kanji conversion using valence "" Hiroshi Yamada, Hiroshi Oyama, Proceedings of National Conference of Information Processing Society of Japan,
1988). In other words, the valence of a noun (verb, adjective, adjective, etc.) is what kind of noun (concrete noun, person, place, etc.) and what kind of particle (ni,
, Etc.), and can be expressed in the form of "type of noun + particle + verb". On the other hand, here, the notation 302 of the synonym search dictionary 5 corresponds to a noun, and the valence information 303 thereof is expressed in an abbreviated form of “noun type + particle” to which the noun connects. . A specific example of using the valence information 303 will be given below. The valence information 303 is a verb only when it is closely related to the part of speech 404 and the noun type 405 of the Kana-Kanji conversion dictionary 2 of FIG. This is the information for searching the synonyms.
It can be seen that the word "caution" of the notation 302 corresponding to the word "caution" shown in FIG. 3 has the valence information 303 of "concrete noun + to (particle)". According to the Kana-Kanji conversion dictionary 2 of FIG. 4, the part-of-speech 404 of “signal” is a noun,
Since the noun type 405 is “concrete noun”, it can be understood that the “attention” of the noun can take “signal” which is “concrete noun” and particle “ni”. On the other hand, if there is a sentence "Be careful of the signal," it can be said that the valence is "a concrete noun + a + verb".

The valence of the input character string including the synonym search designating word which is the source for the retrieval and extraction of the synonym, which is a denomination, is the valence of the part of speech 404 or noun type of the kana-kanji conversion dictionary 2 by the valence search means 6. Recognize by reading 405.
The synonym search means 4 collates the synonym search designated word for which a synonym is searched for with the notation 302 of the synonym search dictionary 5 and extracts the notation 302 belonging to the same group number 301. Next, the valence search means 6 reads the valence information 303 of the extracted notation 302 of the same group number 301 from the synonym search dictionary 5, and the valence information 303 of the input character string including the synonym search designation word. To determine if it matches. The synonym search means 4 searches the synonym search dictionary 5 for synonyms having valence information 303 that matches the valence of the input character string. In this way, by using the valence in the search for the synonyms, only the synonyms that match the valence of the input character string are searched, and unnecessary synonyms are not searched.

The display means 7 displays an input character string for Kana-Kanji conversion, a conversion candidate character string, and a fixed character string, and also displays a search word and a fixed word in the synonym search dictionary 5.

Next, the operation of the document creating apparatus will be described.
FIG. 2 is a flow chart showing an example of the operation of the document creating apparatus of this embodiment.

The operator inputs a character string (step 2
01), when a kana-kanji conversion is performed to search for a noun with another accurate expression when a sentence is being created, the noun + particle, which is the nominative of the noun, is pre-determined and the valence search means 6 Is the valency of the input character string and the part-of-speech 404 of the Kana-Kanji conversion dictionary 2
1 and the noun type 405 are recognized (step 202), and the synonym key 104 of the input means 1 of FIG.
When is pressed, the synonym search means 4 is called (step 203), and when the range of the noun to be searched is designated (step 204), the synonym search designated word in the input character string is received and the notation 302 of the synonym search dictionary 5 is displayed. When searching, when the synonym search designated word matches the notation 302 of the synonym search dictionary 5 (step 205), the synonyms of the same group as the notation 302 are extracted based on the group number 301 (step 206). Next, the valence search means 6 checks whether the valence information 303 is added to the synonym search designation word, and if it is added (step 20).
7) The valence search means 6 checks whether there is a synonym having valence information 303 matching the valence in the input character string (step 208), and valence information matching the valence of the input character string. Only synonyms having 303 are written in the notation means 7 of FIG.
(Step 209). If the valence information 303
Is not added to the synonym search designation word (step 207), all the synonyms of the same group extracted in step 206 are displayed (step 210). Step two
In either case of 09 or 210, if there is even one synonym searched and displayed, if the operator judges that it is appropriate (step 211), the execution key 103 of the input means 1 of FIG. 1 is pressed. The synonym search designation word in the input character string is replaced and output to the display means 7 (step 21).
2). When a plurality of synonyms are retrieved and displayed, the operator selects the synonym that the operator thinks is appropriate by pressing the selection key 105 of the input means 1 in FIG. 1 (step 21).
1) The execution key 103 is pressed to replace the synonym search designation word in the input character string and output it to the display means 7 (step 212). However, in the case where the synonym is one word or a plurality of synonyms, if the operator determines that there is no proper synonym to be replaced with the search designated word in the displayed synonyms, the operator of the input means 1 of FIG. The cancel key 106 is pressed to return to normal kana-kanji conversion.

Finally, two examples of using the synonym search dictionary 5 of FIG. 3 are shown below.

As a first example, let us consider a case where the retrieved synonym is one word. To search for a synonym of "Attention" in the input string "Attention to the signal", after inputting "Shingouni nikyusuru" in the normal Kana-Kanji conversion mode, press the conversion key 102 and Please be careful. ”And make a preliminary confirmation. When the operator tries to search for a synonym of "Caution", the synonym key 1
When 04 is pressed, the synonym search means 4 is called and "caution" is designated as a synonym search designation word, and the synonym search dictionary 5
Look up the "Caution" notation 302 of the group number 30
1 is searched and the word of the same group number 301 is extracted. The search candidates at this point are two words, "be careful" and "warn". Next, since the bond value information 303 is added to "Be careful", the bond value of "Be careful of the signal" which is the input character string is checked. The structure of this input character string is “concrete noun + ni + verb”, and the synonym search dictionary 5 of FIG. 3 searches only “be careful” with the valence information 303 of “concrete noun + ni”. Therefore, “warn” having the valence information 303 of “to person +” is not searched. Therefore,
Only "be careful" is displayed on the display means 7 as a synonym. If the operator determines that the expression "be careful" is correct, he or she depresses the execution key 105 to replace the word "be careful" in the input character string with the searched synonym "be careful". If it is determined that it is not necessary to replace the synonym “be careful” with the word “caution”, the cancel key 106 is pressed to return to the normal kana-kanji conversion.

As a second example, let us consider a case where a plurality of synonyms are selected. When searching for a synonym of "hope" in the input string "hope for peace", after entering "heiwawaganega" in the normal kana-kanji conversion mode, the conversion key 1
Press 02 to convert it to "hope for peace" and make it a preliminary confirmation. When the synonym key 104 is pressed, the synonym search means 4 is called, "hope" is designated as a synonym search designation word, the synonym search dictionary 5 is searched for the "wish" notation 302, the group number 301 is searched, and the word of the same group number 301 is searched. To extract. At this point, the search candidates are three words, "hope", "apply" and "hope". Next, since the bond price information 303 is attached to "hope", the bond price of the input character string "hope for peace" is checked. The structure of this input character string is "abstract concept noun + wo + verb", and the synonym search dictionary 5 in FIG. 3 has "hope" and "wish" with the valence information 303 of "abstract concept noun + wo". Is searched for, but
"Aspiring" having the bond value information 303 of "Organization +" is not searched. Therefore, the display means 7 displays the two words of “hope” and “hope” as synonyms. The operator presses the select key 105 to select the word that is judged to be correct from the two words, and presses the execute key 103 to replace "wish" in the input character string. If it is determined that it is not necessary to replace the synonym “wish” or “wish” with the word “wish”, the cancel key 106 is pressed to return to the normal kana-kanji conversion.

In this way, when searching for synonyms,
By using the valence, it is possible to perform a process in which only synonyms that match the valence of the input character string and the valence information 303 in the synonym search dictionary 5 are searched, and unnecessary synonyms are not searched. Therefore, even an operator who is not accustomed to the document creation device can easily select an appropriate synonym because many synonyms displayed after the search are narrowed down to the synonyms that match the input character string. You can

In the above description, as an example, synonyms are used as words for searching for synonyms, but the invention is not limited to this. For anonym, the synonym key 104 shown in FIG. 1 is pressed twice. By (or pressing the synonym key 104 and other keys at the same time) and designating the synonym search designation word as an antonym, the same effect as described in the above example can be obtained and the object of the present invention can be achieved. Is clear. Further, although the bond value information 303 has been described as an example in which a noun is used as the subject of a noun, the bond value information 303 using another part of speech can also be used.

[0025]

As described above, when the operator refers to the synonym search dictionary for word wording while creating a sentence, the document creating apparatus of the present invention uses the valence to find the structure of the input character string. Since only synonyms can be grammatically searched and displayed, the operator does not have to select synonyms that do not match the structure of the input sentence as in the conventional technique that displays all synonyms. It is possible to obtain the effect that the operator can select a synonym accurately and easily.
